ABSTRACT:
In a reflective liquid crystal display device according to the invention, burn-in in a long-term drive which occurs due to asymmetric structures of side surfaces of an inter-pixel groove can be prevented, and long-term drive reliability can be achieved. A first obliquely evaporated alignment film is formed on a first side surface of the inter-pixel groove in a sectional surface of a pixel electrode substrate in a thickness direction through evaporation, and a second obliquely evaporated alignment film is formed on a second side surface facing the first side surface through evaporation. Thereby, the film structures of both side surfaces of the inter-pixel groove in the sectional surface become symmetric, so burn-in in a long-term drive which occurs due to the asymmetric structures of the side surfaces of the inter-pixel groove can be prevented.
